A comprehensive new national study says that white kids are way more likely to be druggies than either black kids or Asian kids, but the biggest druggies of all are Native American kids. Specifically:

About 9 percent of the white teenagers in the study sample used substances in ways that indicated they had disorders, meaning abuse or dependency. That's nearly twice the percentage of blacks nearly three times the rate for a group classified as Asian/Pacific Islander, which were mostly Asians.. The prevalence of disorders was by far highest among Native Americans, at 15 percent.

Yeah, so, basically, the exact breakdown that existed in your high school. The only group more likely than Native Americans to be on drugs: anyone wearing a D.A.R.E. t-shirt.
